What should I do if I receive network connection error codes on the ET-2800?

Print a network connection report to view specific error codes and messages. Error codes like E-1 indicate connection problems with cables or network devices, while E-2 or E-3 suggest issues finding wireless networks. For E-5 errors, the security mode may not match your router settings. Consult the Network Connection Report Codes and Messages section in the manual for detailed solutions for each error code, which include checking router settings, confirming passwords, and verifying network configuration.
